Celestica Jumps 5.6% To $211.87 Extending 2-Day Rally To 8.79%

Celestica (CLS) concluded the most recent session at $211.87, marking a 5.60% gain and extending its advance to 8.79% over two consecutive trading days. This momentum sets the context for our technical assessment.
Candlestick Theory
Celestica’s price action exhibits a robust recovery pattern following the August 29 bearish engulfing candle (close: $194.75). The subsequent two sessions formed consecutive bullish marubozu-like candles with minimal lower wicks, closing near session highs ($200.63 and $211.87). This indicates strong accumulation pressure. Immediate resistance converges at $212.30 (September 3 high), while $200.00 represents a psychological support floor reinforced by the August 26–28 consolidation range. A sustained break above $212.30 could trigger momentum toward the YTD high of $214.63.
Moving Average Theory
The moving average structure confirms a bullish trend. The 50-day SMA (approximately $183) and 100-day SMA (~$167) slope upward beneath the price, with the 200-day SMA ($135) anchoring a long-term ascending base. Notably, the 50-day SMA crossed above both the 100-day and 200-day SMAs in Q2 2025, establishing a "golden cross" configuration. Current price positioning well above all three key averages signals sustained intermediate and long-term upside momentum. The 50-day SMA now serves as dynamic support.
MACD & KDJ Indicators
MACD (12,26,9) shows a bullish crossover emerging after the indicator approached the zero line from above during the late August pullback. The histogram has turned positive, signaling recovering upside momentum. Concurrently, the KDJ oscillator reflects overbought conditions with the %K line (92) and %D line (88) above 80, historically associated with near-term consolidation. However, the MACD-KDJ divergence observed August 20–28 (price lower lows against higher KDJ lows) correctly anticipated the current rebound, lending credibility to the indicator suite.
Bollinger Bands
Volatility expanded sharply during the late August selloff, with price breaching the lower Bollinger Band (20-day SMA, 2σ) on August 29. The rapid recovery to the upper band ($208) by September 3 denotes aggressive mean reversion. Band width remains elevated relative to June–July levels, suggesting ongoing volatility. Price closure in the upper band quadrant (>20 SMA +1σ) typically implies continuation strength, though mean-reversion pressures may emerge near $212–214.
Volume-Price Relationship
Volume analysis reveals conviction behind the rebound. September 2–3 traded 7.01M shares, exceeding the 30-day average volume by 32%. This expansion during upside sessions contrasts with distribution patterns in late August, where the August 29 selloff occurred on 3.94M shares versus the prior up day’s 1.76M. Elevated volume on advances confirms bullish participation, though resistance tests above $212 require volume validation to sustain breaks.
Relative Strength Index
The 14-day RSI surged to 68 following the recent rally, nearing overbought territory but leaving room for additional upside. Historically, RSI sustained above 60 since early July 2025, confirming the structural uptrend. Divergences have been timely: bearish divergence preceded the August correction (RSI lower high against price higher high), while the oversold dip to 29.5 on August 29 aligned with a swing low. Current readings suggest moderate overextension but no imminent reversal signal.
Fibonacci Retracement
Applying Fibonacci to the August 28 high ($214.63) and August 29 low ($194.75) reveals significant confluence. The 61.8% retracement at $207.11 was breached decisively on September 3, with price now testing the 78.6% level ($211.25). This aligns with horizontal resistance at $212.30, creating a technical pivot zone. A confirmed close above $212.30 projects a full retracement to $214.63+. Support tiers form at the 50% ($204.70) and 38.2% ($202.40) levels, layered over the psychological $200 support.
Confluence & Divergence
Bullish confluence appears at $200, combining the psychological support, 38.2% Fibonacci, and 20-day Bollinger Band. The MACD bullish crossover and volume-backed recovery further strengthen this level. Near-term resistance at $212.30 integrates candlestick highs, the 78.6% Fibonacci, and upper Bollinger Band. Divergence arises between KDJ’s overbought signal and MACD’s nascent bullishness, warranting vigilance for consolidation. However, multi-indicator alignment in trend direction (moving averages, RSI trend, volume) favors bullish resolution pending $212.30 clearance.
